Seto kaiba deck sword soul

Kaiba mainly runs Decks that centralize on a Beatdown strategy to aggressively overwhelm his opponents with high ATK monsters. During the first several arcs of the Yu-Gi-Oh anime, his Deck is composed of vicious-looking monsters, with most of them being DARKFiend-Type. The Spells and Traps in his Deck normally serve to disrupt and counter any strategies his opponents would use.

His monster lineup is spearheaded by his signature card, "Blue-Eyes White Dragon" and its Fusion form, "Blue-Eyes Ultimate Dragon".

In the later arcs, he incorporates "Virus" cards such as "Giant Germ", "Crush Card", and "Virus Cannon" that give it the traits of a Virus Control Deck and swarm Deck, destroying all monsters in his opponent's Deck with more than 1500 ATK, further crippling their ability to defend against him.

As the series evolves, Kaiba's switches his focus towards Dragon-Type monsters.
